Description

Technical Field

[0001] This utility model belongs to the field of mobile sewage sampling technology, and specifically relates to a mobile sewage sampling device. Background Technology

[0002] In the field of wastewater treatment, vacuum trucks are typically used when treating highly viscous wastewater or viscous pollutants such as sludge. The operating procedure involves moving the vacuum truck to the location or storage area of ​​the pollutants (such as a sludge storage tank or sedimentation tank), using the vacuum pump on the truck connected to the discharge pipe to pump the pollutants into the truck's storage tank for temporary storage, and then transporting them to other areas for treatment or disposal.

[0003] However, when the pollutants stored in the sludge tank have high viscosity, the existing technology uses a drain valve for discharge, and the drain valve has a narrow discharge channel, resulting in low discharge efficiency and causing a large amount of viscous pollutants to accumulate in the sludge tank.

[0004] However, when it is only necessary to clean the solid pollutants in the sludge storage tank or sedimentation tank, and there is no need to pump out the sewage, the use of a sludge pump will inevitably require the sewage to be pumped into the sludge storage tank along with the sewage, and it cannot be filtered out and discharged back to its original location, which affects the storage capacity of solid pollutants. Utility Model Content

[0005] This utility model provides a mobile sewage collection device that discharges sewage by tilting the sewage storage tank and then using a screw conveyor, which greatly improves the discharge efficiency of viscous pollutants. It can also use a filter screen to filter out the sewage in the storage tank and discharge it back to the original storage location.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A mobile sludge collection device includes a mobile chassis, a sludge storage tank, and a hydraulic rod. A support is mounted on the mobile chassis and hinged to the middle of the sludge storage tank. A spiral blade is installed inside the sludge storage tank, and the spiral blade is connected to a drive mechanism to rotate within the tank. One end of the sludge storage tank is closed, and the other end is open. A sludge pump is located near the open end of the tank, with its discharge end connected to the inside of the tank and its inlet end connected to a quick connector. A drain valve is located at the closed end of the tank, with a filter screen at its inlet end and a quick connector connected to its discharge end. The hydraulic rod is hinged at both ends to the sludge storage tank and the mobile chassis, respectively.

[0008] Furthermore, the drive mechanism includes a motor located on the closed end of the sludge storage tank and a shaft located inside the sludge storage tank. The spiral blades are located on the shaft, and the motor is connected to the shaft.

[0009] Furthermore, a second support is provided at the open end of the sludge storage tank, and a reduction motor is provided on the second support. The output shaft of the reduction motor is connected to a cover through a connecting rod. The reduction motor can drive the cover to close or open the open end of the sludge storage tank.

[0010] Furthermore, a locking block is provided at the closed end of the sludge storage tank, and a locking groove is provided on the locking block. A hydraulic rod is provided on the first support, and a locking rod is connected to the hydraulic rod. A third support is provided on the movable chassis, and the locking rod slides through the third support. When the sludge storage tank drives the locking block to swing downwards until it abuts against the movable chassis, the locking groove aligns with the locking rod.

[0011] Furthermore, the mobile chassis is a vehicle body.

[0012] Furthermore, the mobile chassis includes a base plate, a plurality of rollers are provided on the lower surface of the base plate, a pusher is provided on the base plate, a hydraulic rod is connected to the base plate, and a support and a support are both provided on the base plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. After the suction pump is connected to the suction pipe via a quick connector, it can extract and transport solid pollutants into the storage tank. After the drain valve is connected to the drain pipe via a quick connector, opening the drain valve allows the filter screen to block solid pollutants, while the sewage can be filtered out by the drain valve and discharged back to its original location, greatly increasing the storage and transportation capacity of solid pollutants.

[0015] Second, when sewage needs to be discharged, the hydraulic rod retracts to tilt the opening of the sewage tank downwards. The drive mechanism then drives the spiral blades to rotate inside the sewage tank, pushing the pollutants towards the opening of the tank, which greatly improves the discharge efficiency of viscous pollutants.

[0016] Third, when discharging pollutants into the storage tank, the drive mechanism can be used to drive the spiral blades to rotate in the opposite direction, so that the pollutants are squeezed, which can improve the filtration efficiency and filtration effect of the pollutants.

[0023] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0024] Example 1

[0025] See Figures 1 to 4 This utility model provides a mobile sludge collection device, including a mobile chassis, a sludge storage tank 8, and a hydraulic rod 5. A support 12 is fixedly installed on the mobile chassis, and the top of the support 12 is hinged to the middle of the sludge storage tank 8. A spiral blade 10 is installed inside the sludge storage tank 8, and the spiral blade 10 is connected to a drive mechanism. The drive mechanism can drive the spiral blade 10 to rotate inside the sludge storage tank 8. One end of the sludge storage tank 8 is a closed structure, and the other end of the sludge storage tank 8 is an open structure. A sludge suction pump 7 is fixedly installed near the open end of the sludge storage tank 8. The sludge discharge end of the sludge suction pump 7 is connected to the inside of the sludge storage tank 8, and the sludge inlet end of the sludge suction pump 7 is connected to a quick connector 2. A sludge discharge valve 3 is installed at the closed end of the sludge storage tank 8. A filter screen 4 is installed on the sludge inlet end of the sludge discharge valve 3, and the sludge discharge end of the sludge discharge valve 3 is connected to a quick connector 2. The two ends of the hydraulic rod 5 are respectively hinged to the sludge storage tank 8 and the mobile chassis.

[0026] When it is necessary to collect sewage, the sewage pump 7 is connected to the sewage suction pipe through the quick connector 2. The hydraulic rod 5 is used to drive the open end of the sewage storage tank 8 to rise to increase the sewage storage capacity. After the end of the sewage suction pipe away from the sewage pump 7 is placed in the pollutant storage area, the sewage pump 7 can be started to extract the pollutants into the sewage storage tank 8.

[0027] If the extracted pollutants contain a lot of moisture and need to be returned to their original location, the drain valve 3 is connected to the drain pipe via the quick connector 2. After placing the end of the drain pipe away from the drain valve 3 into the pollutant storage area, the drain valve 3 is opened, and the moisture in the pollutants can pass through the filter screen 4 and be discharged back to its original location via the drain valve 3 and the drain pipe. Alternatively, the drive mechanism can be used to drive the spiral blades 10 to rotate in the opposite direction to squeeze the pollutants toward the filter screen 4, which can improve the filtration efficiency and filtration effect of the pollutants.

[0028] When sewage needs to be discharged, the hydraulic rod 5 is retracted to tilt the opening of the sewage tank 8 downward. At this time, the pollutants are discharged by gravity. During the sewage discharge process, the drive mechanism drives the spiral blade 10 to rotate inside the sewage tank 8. The spiral blade 10 pushes the pollutants to the opening of the sewage tank 8, which can greatly improve the discharge efficiency of viscous pollutants.

[0029] Specifically, the drive mechanism includes a motor 11 located on the closed end of the sludge storage tank 8 and a shaft 9 located inside the sludge storage tank 8. The spiral blade 10 is located on the shaft 9, and the motor 11 is connected to the shaft 9. The motor 11 can drive the shaft 9 to rotate inside the sludge storage tank 8, and the shaft 9 can drive the spiral blade 10 to rotate inside the sludge storage tank 8. Furthermore, by controlling the output direction of the motor 11, the rotation direction of the spiral blade 10 can be selected and controlled during sludge storage or discharge.

[0030] Specifically, a support 2 15 is fixedly installed at the open end of the sludge storage tank 8. A worm gear type reduction motor 14 is fixedly installed on the support 2 15. The output shaft of the reduction motor 14 passes through the support 2 15 and is connected to the cover 6 through the connecting rod 13. The reduction motor 14 can drive the cover 6 to close or open the open end of the sludge storage tank 8, and can also ensure that the cover 6 remains in the current position when the reduction motor 14 stops working. After the sludge storage is completed, its open end needs to be closed to prevent pollution from leaking out from the open end during transportation.

[0031] Specifically, a locking block 16 is fixedly installed at the closed end of the sludge storage tank 8, and a locking groove 17 is provided on the locking block 16. A hydraulic rod 19 is fixedly installed on the support 12, and a locking rod 20 is fixedly connected to the telescopic end of the hydraulic rod 19. A support 3 18 is fixedly installed on the movable chassis, and the locking rod 20 slides through the support 3 18. When the sludge storage tank 8 drives the locking block 16 to swing downwards until it abuts against the movable chassis, the locking groove 17 aligns with the locking rod 20, and the hydraulic rod 2 19 can drive the locking rod 20 to insert into the locking groove 17. With the cooperation of the support 3 18, the sludge storage tank 8 can be locked, avoiding excessive back-and-forth swinging during transportation and damage to the hydraulic rod 15.

[0032] Specifically, the mobile chassis is vehicle body 1, which can be purchased from existing light truck Class II chassis on the market, suitable for large-scale sewage extraction operations.

[0033] Example 2

[0034] See 5, the difference from Example 1 is:

[0035] Specifically, the mobile chassis includes a base plate 101, with multiple rollers 102 rotatably mounted on the lower surface of the base plate 101. A pusher 103 is fixedly mounted on the base plate 101, a hydraulic rod 5 is connected to the base plate 101, and supports 12 and 3 are both fixedly mounted on the base plate 101. This design differs from Embodiment 1 in that it is suitable for a small number of wastewater sampling operations. After the wastewater sampling is completed, the pusher 103 is manually pushed to move the chassis. Although it has high mobility, it is not suitable for a large number of wastewater sampling operations.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
